My first script in home assistant

The first post here. And my first script in Home Assistant. I have installed Mopidy and Snapcast on my server and have a couple of orange pi's to run snapcastclient to get multiroom audio.

On the bathroom I have this orange pi with a 433mhz plug switch connected to the Aux in on my Pinell Supersound II Radio. I want to have a switch on the Home Assistant UI to turn the orange pi and pinell on and select the right source on the radio.

Some googling and trial and error.. I found that this is working:

I have this in the scripts.yaml file:

musikk_bad_on:

    alias: musikk bad on
    sequence:
      - service: media_player.turn_on
        entity_id:
          - media_player.pinell_supersound_002261086da2
      - service: switch.turn_on
        entity_id:
          - switch.musikk_bad_switch
      - service: media_player.select_source
        data:
           entity_id: media_player.pinell_supersound_002261086da2
           source: 'AUX inngang'

musikk_bad_off:
         
    alias: musikk bad off
    sequence:
      - service: media_player.turn_off
        entity_id:
         - media_player.pinell_supersound_002261086da2
      - service: switch.turn_off
        entity_id:
          - switch.musikk_bad_switch

And I did put this under switch in my configuration.yaml file.

  - platform: template
    switches:
      musikkbad:
        friendly_name: "Musikk bad"
        value_template: "{{ is_state('switch.musikk_bad_switch', 'on') }}"
        turn_on:
          service: script.turn_on
          entity_id: script.musikk_bad_on
        turn_off:
          service: script.turn_on
          entity_id: script.musikk_bad_off
